Testable switched-capacitor filters

IEEE Journal of Solid-State Circuits, 1992
A design-for-testability (DFT) methodology for switched-capacitor (SC) filters is presented, based on an architecture using some additional circuitry and providing extra capabilities for both off- and online test. A programmable biquad is used for on-chip comparison of the transfer functions for every filter stage.

1V switched-capacitor filters

1999
In the last years the interest toward low-power low-voltage integrated systems has consistently grown due to the increasing importance of portable equipment and to the reduction of the supply voltage of modern scaled-down technology IC [1, 2]. In such systems, a number of analog functions can be efficiently implemented with SC technique which ensures ...

Switched-capacitor filters

20th Annual IEEE Power Electronics Specialists Conference, 1990
A novel technique for building active filters using switched-capacitor (SC) circuits is proposed. The principle of operation, methods of control, and analysis and design of a typical SC filter are presented. To assess its effectiveness, the technique is used to control input current harmonics in a phase-controlled converter. It is shown that by using a

MOS switched-capacitor filters

Proceedings of the IEEE, 1979
In the past several years, much progress has been made in bringing the economies of integrated-circuit technology to bear on the realization of voiceband frequency selective filters. This paper will review one approach to this problem, the use of switched-capacitor techniques.

Switched-capacitor lattice filters

[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems, 2002
The authors present a set of direct implementations of lattice filters using switched capacitor techniques. They discuss both FIR (finite impulse response) and AR versions of the lattice topology. The circuits described possess all the properties of their digital counterparts such as designing directly in the digital domain and exhibiting a uniform ...
